Power BI

What is Power BI

Power BI is a business intelligence and data visualization tool from Microsoft. It allows users to connect to a wide range of data sources, and create interactive reports and dashboards.


1. Data Integration and Transformation: 

Power BI can connect to a wide variety of data sources. These include SQL databases, Excel spreadsheets, and cloud services. It allows users to transform and clean the data to create a coherent data model.

2. Data Modeling: 

Users can create relationships between different data sources, and define hierarchies. It includes a variety of data analysis tools, such as DAX (Data Analysis Expressions) and machine learning algorithms.

3. Data Visualization: 

It provides a range of data visualization options, including charts, graphs, and maps. Users can create interactive dashboards and reports to represent data insights visually.

4. Publishing and Sharing: 

Reports and dashboards created in Power BI can be published to the Power BI service. Users can also embed reports in websites and apps.

5. Natural Language Query: 

 Its Q&A feature allows users to ask natural language questions about their data. The tool is able to generate the appropriate visuals in response.

6. Mobile Accessibility: 

Power BI can be viewed through mobile apps for iOS and Android. This allows users to access their data and reports anywhere. 

7. Security and Governance: 

It provides features for data security and governance, including role-based access control, data encryption, and auditing.


Power BI consists of several components that work together to enable users to connect to, visualize, and analyze data. These components include:

  • Power Query: Power Query is a data transformation tool. It allows users to clean, shape, and merge data from a variety of sources.
  • Power Pivot: Power Pivot is a data modeling tool that allows users to create in-memory data models for analysis.
  • Power View: Power View is a data visualization tool that allows users to create interactive reports and dashboards.
  • Power Map: Power Map is a data visualization tool that allows users to create geographic visualizations of their data.
  • Power Q&A: Power Q&A is a natural language query tool. Using it one can ask questions about the data in plain English.
  • Power BI Desktop: Desktop is an application that allows users to create and edit BI reports.
  • Power BI Service: Power BI Service is a cloud-based service. It allows users to publish and share BI reports and dashboards.
  • Power BI Mobile Apps: BI Mobile Apps allow users to view reports on their mobile devices.

These components can be used together to create a complete BI solution. 

For example: 

  • Power Query can be used to clean and transform data from a variety of sources
  • Power Pivot can be used to create a data model
  • Power View can be used to create interactive reports and dashboards
  • Finally, Power BI Service can be used to publish and share the reports and dashboards with others.
